I got the impression from OP and her follow up that she wanted something more mature. Easy enough to pick up a cheap night out dress but investing in a classic dress to wear for professional or events (not hanging out with friends) is a logical choice. To me, an LBD is a wardrobe staple that’s lines will last and can accessorized to fit different occasions. For this, she might need a dress for a cocktail party with her parents or an interview or on a fancy date (yes, some college kids do that) with some killer heels .
Also, OP asked for dresses for her. So, some of mine were dresses that I thought OP might like more.
Everyone has a different fashion style too. To some teens, they just might gravitate towards more mature styles. Nothing wrong with either fashion sensibility.
